OX NCBI_TaxID=41396; RN [1] RP NUCLEOTIDE SEQUENCE. RA Volkaert H.A.; RT "Chloroplast DNA sequence of teak (Tectona grandis L. f.) and its RT diversity."; RL Submitted (NOV-2012) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Apoprotein for the two 4Fe-4S centers FA and FB of CC photosystem I (PSI); essential for photochemical activity. FB is CC the terminal electron acceptor of PSI, donating electrons to CC ferredoxin. The C-terminus interacts with PsaA/B/D and helps CC assemble the protein into the PSI complex. Required for binding of CC PsaD and PsaE to PSI. PSI is a plastocyanin-ferredoxin CC oxidoreductase, converting photonic excitation into a charge CC separation, which transfers an electron from the donor P700 CC chlorophyll pair to the spectroscopically characterized acceptors CC A0, A1, FX, FA and FB in turn (By similarity). CC -!- CATALYTIC ACTIVITY: Reduced plastocyanin + oxidized ferredoxin + CC light = oxidized plastocyanin + reduced ferredoxin. CC -!- COFACTOR: Binds 2 4Fe-4S clusters. Cluster 2 is most probably the CC spectroscopically characterized electron acceptor FA and cluster 1 CC is most probably FB (By similarity). CC -!- SUBUNIT: The eukaryotic PSI reaction center is composed of at CC least 11 subunits (By similarity). CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane; CC Peripheral membrane protein; Stromal side (By similarity). CC -!- SIMILARITY: Contains 2 4Fe-4S ferredoxin-type domains.
